A comprehensive forecast of water inflow in karst tunnels——Exemplified by the Zhujiayan karst tunnel

Water inflow in Karst tunnels has long been a big problem during domestic and international tunnel construction processes,since it will usually cause great damage to such project.Based on recent karst hydrogeology theories and engineering practices both home and abroad,as well as years of experiences,we propose "the four-step modeling method of the comprehensive forecast of the water inflow in karst tunnels".This method uses the theories and methods of Earth System Science and the system theory ...
